A-Premium A/C Discharge Line Hose for Hyundai Sonata & Kia Optima 2.4L — OE-fit, 4-layer Durability

A-Premium A/C Discharge Line Hose Assembly replaces the high-pressure line from compressor to condenser for select 2.4L Hyundai Sonata and Kia Optima models, restoring proper air-conditioning flow and durability.

This A-Premium discharge hose is built as a direct-fit replacement for naturally aspirated 2.4L gasoline engines in specified Hyundai Sonata and Kia Optima model years. Designed to match OE routing and connection points, it carries refrigerant under high pressure between the compressor and condenser. The assembly’s four-layer construction improves resistance to wear, heat, and collapse compared with single-layer hoses, and it is sold with a one-year unlimited-mileage warranty for added confidence.

Which vehicles and engines does this hose fit?

This hose is compatible only with 2.4L gasoline, naturally aspirated engines in specific model years of the Hyundai Sonata and Kia Optima. It does not fit 2.0L or 1.6L engines, hybrid systems, or electric vehicles. Always confirm your VIN engine code when ordering.

• Hyundai Sonata: 2011–2014, L4 2.4L (VIN: C, DI)
• Kia Optima: 2011–2015 various 2.4L fits (VIN: 7) including GDI, MFI, DI depending on year
• Reference part numbers: HA111430C, HA 111430C, 977623R000

How is the hose constructed and why does that matter?

The assembly uses a multi-layer design engineered to withstand the pressures and temperatures typical in automotive A/C systems. Multiple layers add structural support, reduce the chance of collapse under vacuum or high pressure, and extend service life compared with basic hoses. That results in more consistent refrigerant flow and fewer premature failures.

• Four-layer hose construction for improved durability and collapse resistance
• Wider operational temperature range for hot and cold climates
• Factory-style connectors and fittings to match OEM routing

What does installation involve and what should I check?

Installation replaces the high-pressure discharge line between the compressor and condenser and generally requires basic A/C system service knowledge. Have a qualified technician evacuate and recharge the refrigerant to meet safety and environmental rules. Inspect mating O-rings and fittings and replace them if worn to prevent leaks.

• Professional A/C evacuation and recharge recommended
• Verify connector alignment and clamp torque to OEM specs
• Replace seals and inspect adjacent components for wear

What warranty and support does A-Premium provide?

A-Premium backs this A/C discharge hose with a one-year unlimited-mileage guarantee covering manufacturing defects. The company also offers customer support for fitment questions to help ensure you order the correct part number for your vehicle. Keep proof of purchase for warranty service.
